Abstract:
An engine with a supercharger includes a low pressure loop EGR apparatus. An EGR passage having an inlet connected to an exhaust passage downstream of a turbine and an outlet connected to an intake passage upstream of a compressor. An intake bypass passage is provided to bypass the intake passage downstream of the compressor and the intake passage upstream of the compressor, with an ABV in the intake bypass passage. A throttle valve is closed during stop or deceleration operation of the engine. An electronic control unit (ECU) is configured such that, when the ECU determines based on an operation state of the engine that the EGR valve is in a valve-opened state and the engine is in deceleration operation from a supercharging region, the ECU controls an EGR valve to close and the ABV to open from a valve-closed state delayed from start of closing the EGR valve.
